Definitions

  • This invention relates to soap wrappers and, in particular, to a bar of soap wrapped by at least a stiffening member and to a package comprising the bar of soap, the stiffening member and a wrapper entirely surrounding both the bar of soap and the stiffening member.
  • a normal board stiffener when it becomes wet from moisture will significantly loose strength. The ability to protect the soap during transit will therefore be reduced.
  • the stiffener comprises of an inner board and two outer surfaces of a plastic material, moisture uptake by the board will be reduced, and subsequent loss in stiffness will be reduced.
  • a wrapper, wrapped around each of the bar of soap and stiffening member comprises a film material having at least respective outer surfaces thereof each provided by a plastics material, mould growth on and within it can be entirely eliminated.
  • the present invention provides a bar of soap having, wrapped, laterally of the bar, around at least a longitudinal extent of the bar, a stiffening member comprising a stiff sheet material having at least respective outer surfaces thereof each provided by a plastics material, wherein at least part of the stiffening material is transparent.
  • a stiffening member at least a portion of which is transparent, allows the soap to be viewed through the stiffener.
  • the use of conventional paper loaded stiffeners has prevented the provision of see-through stiffeners.
  • the provision of plastic stiffeners provides improved resistance to mould attack.
  • the stiffness of the stiffening member is at least 3 Taber Stiffness Units in each of the longitudinal (machine) and transverse (cross) directions, and more preferably at least 8 Taber Stiffness units.
  • the stiffening member preferably has a grammage (weight per unit area) of 100 to 200g/m 2 , and preferably has a thickness of 50 to 250 ⁇ m, more preferably 160 to 180 ⁇ m.
  • the entire stiffener member comprises a transparent material, as may the entire wrapper.
  • the invention provides a package comprising a bar of soap and packaging material, which packaging material comprises a stiffening member wrapped, laterally of the bar, around at least a longitudinal extent of the bar, which stiffening member comprises a stiff sheet material having at least respective outer surfaces thereof each provided by a plastics material and including at least a transparent part; and a wrapper, wrapped around, in a manner such as entirely to surround, each of the bar of soap and stiffening member, which wrapper comprises a film material having at least a transparent part.
  • at least respective outer surfaces thereof are each provided by a plastics material.
  • the sheet material of the stiffening member may be a laminate having a core layer of a paper board and respective outer layers each comprising a layer of thermoplastics material, preferably each having a respective thickness, independently of one another, of from 5 to 35 ⁇ m.
  • the entire sheet is of a thermoplastics material, which may contain from 5 to 30%, preferably 10 to 25%, more preferably about 20%, by weight of the total weight of the stiffening member of a filler or blowing agent, or total of filler and blowing agent.
  • the filler is an inert inorganic filler such as talc or clay. Such fillers provide improved stiffness.
  • the thermoplastics material of the stiffening member sheet material is preferably selected from the many types of films suitable for this application. Typically this would be polypropylene, polystyrene, acrylic/butadiene/styrene copolymer and polyethylene terephthalate and PVC. These films may have been either through a mono or bi-orientation process to improve the properties such as clarity, barrier, stiffness etc normally conferred by these processes. However simple case films could be used. The films will preferably be in a form to give maximum stiffness, and typically therefore a suitable polystyrene would either be BOPS or HIPS and a suitable PET would be A-PET.
  • the stiff sheet material is free from memory, so that it does not unfold from a roll on which it was stored, and so that it can be folded around the bar of soap, preferably around the entire peripheral longitudinal surface, of the soap bar, after which the stiffening member will remain in the folded condition so as to define a sleeve surrounding the bar of soap.
  • longitudinal ends of the bar of soap are not surrounded by the stiffening member, so that the bar of soap can be easily removed for use.
  • the wrapper may be a film material comprising a paper core coated on each surface with a plastics material.
  • the wrapper is a film material which is entirely of plastics material, more preferably thermoplastics material, having at least parts of which are transparent.
  • a film with one surface metallised could be used to enhance visual appearance or improve barrier properties. Additionally this could partially be removed to produce a transparent area forming a window through which the soap can be seen.
  • the film material of the wrapper preferably has a thickness of from 5 to 50 ⁇ m.
  • the wrapper when wrapped around the bar of soap and stiffening member, has edge portions in overlapping relationship with one another. This allows those edge portions to be secured to one another. This can be achieved by application of an adhesive between various respective opposite surface regions, for example, by coating the adhesive at various regions of the edge portions, folding the wrapper and applying pressure.
  • edge portions are secured to one another by heat sealing, so that at least outer layers of the film material of the wrapper are preferably of heat sealable plastics material.
  • edge portions are preferably kept free of printing material etc.
  • the film material of the wrapper comprises at least one layer of a biaxially oriented polypropylene capable of heat sealing. More preferably the film is a laminate of a biaxially oriented polypropylene layer with a low density polyethylene film.
  • a package according to the invention containing a soap bar can be produced by a method comprising the steps of:
  • the stiffening member is preferably formed by casting a molten film of thermoplastics material such as polypropylene or polystyrene.
  • a soap wrapping system of a package embodying the invention may comprise:
  • Stiffener materials at least part of which are transparent:
  • wrapper and stiffener materials can be used in any combination with one another.
  • wrapper system be entirely paper free.
  • stiffness values were determined using a Digital Taber V-5 Stiffness Tester (model 150-D) on ten samples each cut to a size of 40 mm x 70 mm, five cut in the transverse and five in the machine direction. Before testing, the samples were preconditioned at 23°C/50% RH for twenty four hours. For the significance of the Taber Stiffness Units, see TAPPI Standard T489 om-86.
  • a Sabouraud Dextrose Agar was employed as a medium for promoting the growth of moulds.
  • This consists of a mixture of mycological peptone (commercially available from Oxoid Ltd., England as Oxoid L40) (10g), dextrose (40g) and agar (15g).
  • This mixture is commercially available from Oxoid Ltd in powder (CM40) or table (CM42) form. For use, it is mixed with 1000 ml of distilled water and autoclaved for twenty minutes at 110°C and cooled to give a growth medium having a pH of 5.6.
  • test packaging material Small squares of test packaging material were cut using scissors dipped in alcohol, flamed and cooled. The squares were placed right side up and upside down onto the surface of poured petri dishes of Sabourauds dextrose agar using flamed, alcohol dipped tweezers.
  • mould inoculum approximately 10 8 spores ml -1 .
  • the inoculum was spread evenly over the surface of the agar and the packaging material.
  • the petri dishes were incubated at 28°C for one week and the level of fungal growth on the packaging material and the agar assessed visually.
